Description of the Related Art Conventionally, inventions related to multilingual information retrieval using one language have been made so that information such as documents described in various languages can be retrieved using one language. For example, in Patent Document 1 described later, a search request (keyword) entered by a user in his / her native language is translated into one or more foreign languages, and a multilingual text database is simultaneously searched using those search requests. An invention of a multilingual information retrieval system is disclosed. Further, it is described that the multilingual search system described in Patent Document 1 has a function of translating different language information included in the search result into the user's native language and providing a unified language. .

JP 2003-76710 A

  In recent years, high-function mobile phone terminals called smartphones, which have become widely used, can select a language (display language or input language) from about 40 languages, and users usually use it. The language is set as the language used. Visitors from other countries also bring in information terminals such as notebook personal computers and tablet terminals that they normally use when they come to Japan. In addition, even when visitors from other countries procure information terminals in Japan, the IME (Input Method Editor) is changed so that the native language can be input, and the language type of the normal application or OS (Operating System) is changed. Change to your native language. Thus, in Japan, many information terminals whose language is not Japanese have been used. In Japan, it is often impossible to search for useful information unless the search site is for Japanese. Therefore, instead of multilingual information retrieval in one language as described in Patent Document 1 described above, it is possible to retrieve information expressed in Japanese using various languages. A need has arisen for word information retrieval.

  Therefore, by applying the technology related to single language-multilingual information search as described in Patent Document 1 described above, a multilingual search database expressing search information in multiple languages is created. It is possible to enable a search. In this case, since there are various languages used by the terminal device of the search source, it is necessary to provide a plurality of search keyword input pages corresponding to each language on the search site side. However, it takes time and effort to prepare a multilingual search database that expresses search information in multiple languages. In addition, if a user has to select a page corresponding to the language used by his / her terminal device from a plurality of search keyword input pages corresponding to each language, the use of the user may be restricted. Absent. Such problems related to multilingual information retrieval are similarly occurring not only in Japan but also in other countries.

  In view of the above, an object of the present invention is to make it possible to use a search service that performs a search in a predetermined language easily and reliably using various languages. To do.

In order to solve the above-mentioned problem, the search server device according to the first aspect of the present invention provides:
A search server that accepts a search character string in a first language used in the terminal device from a terminal device and performs a search in a second language that is different from the first language,
Discrimination means for discriminating a language type of the first language used in the terminal device based on information included in the access request transmitted from the terminal device;
And providing means for providing a page to a language part of the user interface of the page for inputting the search string, the first language of the language type discriminated by said discriminating means to said terminal apparatus,
Searching the second language using the search character string of the first language that is input through the page provided to the terminal device by the providing means and transmitted from the terminal device in the own device . A first translation means for translating into a character string ;
Search means for executing a search process on a facility using the search character string in the second language translated by the first translation means and obtaining a search result;
Storage means for storing information indicating information to be preferentially provided for each language type of the first language;
For the search result expressed in the second language obtained by the search means, based on the information in the storage means, information to be preferentially provided is positioned higher and forms a search result to be provided Forming means;
The terminal device translates the search result to be provided expressed in the second language formed by the forming unit into the first language according to the language type determined by the determining unit, And a second translation means provided in the above.

  As a result, no matter how many words the search character string is from the terminal device, search processing is performed in a predetermined search language that is determined in advance, and the search result is language information according to the language used by the terminal device. Can be provided to the user of the terminal device. That is, the search server device can search for information expressed in one language that supports multiple languages (one language information search that supports multiple languages).

  There is still a mechanism for discriminating the region (region) of the access source from the IP address and matching the site to the language of the region (country). However, in the case of the present invention, the above-described configuration realizes a mechanism for determining the language set in the access source terminal device (visitor's site browsing device) and matching the site to that language. This makes it possible to reliably determine the language type of the language (use language) used in the terminal device, even if it is a terminal device procured in the visited country, without depending on the IP address, and adjust it to the use language. Can provide a site.

  A search service for searching in a predetermined language can be used easily and reliably using various languages. That is, a single language information search corresponding to multiple languages can be performed easily and reliably.

It is a figure for demonstrating the search server apparatus 1 and the terminal device 3 of embodiment. FIG. 10 is a diagram for describing an example of language-based priority provision / non-provision information setting data registered in the storage device 103. 4 is a flowchart for explaining a search service providing process in the search server device 1; It is a flowchart following FIG. It is a figure for demonstrating the example of the search reception page which receives a search character string. It is a figure for demonstrating the example of a display of a search result.

  Hereinafter, embodiments of the apparatus, method, and program of the present invention will be described with reference to the drawings. The present invention can be applied when searching a search database prepared in various languages. In other words, it can be implemented in various countries around the world. However, in the following, for the sake of simplicity of explanation, a case where a search database prepared in Japanese in Japan is searched will be described as an example.

  FIG. 1 is a diagram for explaining a configuration example of the search server device 1 of this embodiment that provides a search site and a configuration example of a terminal device 3 that uses the search site. The search server device 1 and the terminal device 3 are connected through the network 2. The network 2 is mainly the Internet, but also includes various wide-area networks such as a telephone network and a mobile phone network that provide a path for connecting the Internet to the search server device 1 and the terminal device 3. Although only one terminal device 3 is shown in FIG. 1, a large number of terminal devices 3 can actually access the search server device 1 through the network 2.

[Configuration Example of Search Server Device 1]
The search server device 1 includes a communication I / F 101, a control unit 102, a storage device 103, a crawling unit 104, a search database (hereinafter referred to as a search DB) 105, as shown in the block diagram on the upper end side of FIG. A multilingual dictionary 106 is provided. The search server device 1 also includes a language type determination unit 107, a search processing unit 108, a UI (User Interface) display change unit 109, a search character string translation unit 110, and a search result translation unit 111.

  The communication I / F 101 converts a signal received through the network 2 into data that can be processed by the own device and captures the data. In addition, the communication I / F 101 converts various data for transmission into signals conforming to the protocol and transmits the signals to the network 2. The control unit 102 controls each unit of the search server device 1 and is configured by connecting a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) through a CPU bus (not shown). Computer device.

  The storage device 103 is a hard disk drive (HDD) that includes a hard disk as a recording medium and performs writing / recording holding / reading / deleting various application programs and data obtained by various processes. Further, the storage device 103 holds page information (information forming each page) constituting the search site. The page information includes a search reception page for receiving an input of a search character string (search keyword). For visitors from other countries, there is information that should be provided preferentially and information that should not be provided on the contrary as information obtained as a result of the search. In order to cope with this, preferential registration / non-provision information setting data for each language is registered in advance in the storage device 103 of this embodiment.

  FIG. 2 is a diagram for explaining an example of language-based priority provision / non-provision information setting data registered in the storage device 103. According to the language used by the terminal device 3 that has accessed the search site, the preferential provision / non-provided information setting data for each language is preferentially provided or not provided among the information obtained as a result of the search. This is setting information for filtering processing of information to be made. As shown in FIG. 2, the language-specific priority provision / non-provision information setting data includes a language type, a priority provision information type, and a non-provision information type.

  In general, drug stores, 100-yen shops, and consumer electronics mass retailers are popular with travelers from Asia including China. Also, if you stay in a foreign country for more than 5 days, you tend to want to eat your own food. For this reason, in the example of priority-based provision / non-provision information setting data according to language shown in FIG. 2, for a user of a terminal device that uses Chinese as a language, a drug store, a 100-yen shop, a home appliance mass retailer, a Chinese restaurant Is set as a priority to be provided. In FIG. 2, the three-digit number is identification information for each information type determined in advance corresponding to each information type.

  For the same reason, for users who use Arabic as a working language, information regarding home appliance mass retailers and Arabic restaurants should be preferentially provided. In countries that use Arabic, many people do not drink or eat pork for religious reasons. For this reason, the information regarding liquor stores, pubs, bars, pork cutlets, and pork restaurants is set not to be provided.

  For the same reason, for users who use Hindi as a language, information regarding home appliance mass retailers and Indian restaurants should be preferentially provided. In countries that use Hindi, many people do not eat beef for religious reasons. For this reason, information regarding yakiniku restaurants, sukiyaki restaurants, and beef restaurants is set not to be provided. Based on such language-specific priority provision / non-provision information setting data, search result provision (output) control according to the language used can be performed.

  The crawling unit 104 accesses the network 2 through the communication I / F 101, refers to various sites disclosed on the network 2, collects necessary site information, and stores the information in the search DB 105. The search server device 1 of this embodiment provides information on sites of commercial facilities such as restaurants, hotels, and various stores in Japan. For this reason, the crawling unit 15 includes URLs of various commercial facilities in Japan, information indicating the content of the site, various Japanese search keywords obtained by analyzing the content of the site, and the like. Information is stored in the search DB 105. The information indicating the contents of the site includes information types such as drug stores and 100-yen shops as shown in FIG.

  The search DB 105 stores and holds the crawling information collected by the crawling unit 104 as described above, including URLs of various commercial facilities in Japan, information indicating the contents of the sites, and various search keywords in Japanese. To do. The search DB 105 is created on a large-capacity recording medium such as a hard disk. The multilingual dictionary 106 translates search character strings in various languages provided from various terminal devices 3 into Japanese, and uses the search results in Japanese in the language used by the terminal device 3 that is the search request source. And stores language information (dictionary information) in various languages for translation into a language.

  The language type discriminating unit 107 discriminates the language type of the language used in the terminal device 3 that has accessed the own device, based on information included in access requests from various terminal devices 3 received through the communication I / F 101. . Note that the method for determining the language type differs depending on whether the terminal device 3 as the access source is a personal computer, a tablet terminal, or a high-function mobile phone terminal called a smartphone.

  When a personal computer or a tablet terminal transmits / receives data via the Internet, information on the OS, IME, and browser used in these devices is included in transmission information formed according to HTTP (HyperText Transfer Protocol). That is, information indicating which language the OS, IME, and browser are for is described in the transmission information formed according to HTTP. In the case of a high-function mobile phone terminal, since it is originally a global terminal, there is no concept of language type in the OS, browser, etc., unlike personal computers and tablet terminals. Therefore, in the case of a high-function mobile phone terminal, so-called user agent information including information such as application name, version, OS, and language used is included in the transmission signal formed according to HTTP.

  Thereby, the language type discriminating unit 107 confirms some information included in the access request (transmission signal) created and transmitted from the terminal device 3 according to HTTP, thereby determining the language used by the terminal device 3. Language type can be determined appropriately.

  The search processing unit 108 basically extracts information matching the search character string from the search DB 105 using the Japanese search character string (search keyword) input through the above-described search reception page. As a search result. The UI display change unit 109 changes the language portion (character portion) of the user interface of the search reception page according to the language type of the language used by the terminal device 3 that has accessed the search site provided by the search server device 1. The changed search acceptance page is provided to the access source terminal device 3.

  In addition, the search character string translation unit 110 uses the multilingual dictionary 106 to display a search character string other than Japanese received through the search reception page according to the language type of the language used by the terminal device 3 that has accessed the search site. Use to translate into Japanese. The search character string translated into Japanese by the search character string translation unit 110 is supplied to the search processing unit 108 through the control unit 102 and used for the search processing. In addition, the search result translation unit 111 uses the multilingual dictionary 106 as the language of the language type determined by the terminal device 3 that has accessed the search site, using the Japanese search result obtained by the search processing by the search processing unit 108. This is translated and provided to the terminal device 3 that is the access source.

  The search server device 1 of this embodiment having such a configuration provides a search service for information related to commercial facilities in Japan as described above. Accordingly, the basic function of the search server device 1 is that when the access request to the search site is received through the communication I / F 101, the control unit 102 reads the Japanese search reception page from the storage device 103, and this is read as the access source Provided to the terminal device through the communication I / F 101. Then, the control unit 102 of the search server device 1 receives provision of the Japanese search character string input through the search reception page provided to the access source terminal device, and the search processing unit 108 stores the stored information in the search DB 105. The corresponding information is searched from. It is a thing.

  However, the search server device 1 according to this embodiment appropriately responds to an access request from a terminal device 3 whose language is not Japanese. That is, based on the access request from the terminal device 3, the language type determination unit 107 determines the language type of the language used by the terminal device 3 that is the access source. Then, the UI display changing unit 109 functions to provide the Japanese display portion of the UI portion of the Japanese search reception page by changing the UI display portion according to the language used by the terminal device 3 that is the access source, and the terminal device. The search character string can be appropriately input according to the language used in (3).

  Further, the search server device 1 accepts the provision of the search character string of the language used by the terminal device 3 input through the search acceptance page provided to the access source terminal device, and the search character string translation unit 110 receives the search character string from Japan. Convert to word search string. Using the search character string converted into Japanese, the search processing unit 108 searches the corresponding information from the stored information in the search DB 105. Since the search result obtained by the search processing performed by the search processing unit 108 is a search result in Japanese, the search result translation unit 111 translates this into the language used by the terminal device 3 that is the access source, and translates the search result. Is provided to the terminal device 3 of the access source.

  The search result obtained by the search process of the search processing unit 108 includes various information. For this reason, the control unit 102 should preferentially provide the information included in the search result based on the language-specific priority provision / non-provision information setting data shown in FIG. Identify information and information that is not provided. Information that should be preferentially provided is positioned higher in the search results, and information that is not provided is excluded from the search results. Thereby, filtering processing based on the language-specific priority providing / non-providing information setting data described with reference to FIG. 2 can be performed on the search result.

  In addition, each commercial facility site may advertise the presence of staff who can speak a given language, or conversely, it may indicate that a given language is not available. . Therefore, the control unit 102 confirms the search result of the search processing unit 108 and preferentially provides information on the site of the commercial facility indicating that there is a staff who can handle the language used by the terminal device of the access source. . On the other hand, information on the site of a commercial facility that indicates that the language of the terminal device of the access source cannot be handled is excluded from the search results, or the display order is delayed so that only Japanese and English can be handled. Such processing can also be performed.

  Thus, in the search server device 1 of this embodiment, the search processing is performed by the language type determination unit 107, the search processing unit 108, the UI display change unit 109, the search character string translation unit 110, and the search result translation unit 111. To work. As a result, a search string in a language corresponding to the language used by the terminal device 3 that is the access source is received, the Japanese search DB is searched, and the search result is translated into the language used by the terminal device 3 that is the access source. The original terminal device 3 can be provided.

  In other words, the search server device 1 according to this embodiment is set in the access source terminal device, unlike the mechanism that determines the region (region) of the access source from the IP address and matches the site to the language of the region (country). The system that matches the site to the language is identified. As described above, the search server device 1 according to the present embodiment realizes multilingual single language information search according to the language used in the access source terminal device.

[Basic configuration of terminal device 3]
As described above, the terminal device 3 that can access the search site provided by the search server device 1 includes high-function mobile phone terminals called personal computers, tablet terminals, and smartphones. Although these details are different, the portion related to the use of the search site basically has the same configuration. For this reason, here, a basic configuration of a portion related to use of a search site in various terminal devices will be described.

  As shown in the lower block diagram of FIG. 1, the terminal device 3 includes a communication I / F 301, a control unit 302, a storage device 303, an operation unit 304, a display unit 305, a voice processing unit 306, a speaker 307, and a language type notification. A processing unit 308 is provided.

  The communication I / F 301 and the control unit 302 are configured in the same manner as the communication I / F 101 and the control unit 102 of the search server device 1 described above, and have the same functions. The storage device 303 includes a recording medium, and is common in that it has a function of writing / recording holding / reading / deleting various application programs and data obtained by various processes to the recording medium. However, the recording medium used may be a hard disk or a non-volatile memory.

  The operation unit 304 is a part that receives an operation input from the user. Specifically, when the terminal device 3 is a personal computer, it is a keyboard or a mouse (pointing device). When the terminal device 3 is a tablet terminal or a high-function mobile phone terminal, a touch panel affixed to the display screen of the display unit 305. And hardware keys provided on the housing. The display unit 305 displays various display information such as input information and search results. In addition, the sound processing unit 306 and the speaker 307 emit various warning sounds and, when the terminal device 3 is a high function mobile phone terminal, emit a ring tone.

  If the language type notification processing unit 308 does not include the language type of the language used in the own device in the access request to the search site, the language type notification processing unit 308 performs processing to include the language type. For example, when the terminal device 3 is a high-function mobile phone terminal and the user agent information including the language type of the language used is not normally included in the access request to the search site, the user agent information is included in the access request I do. Of course, even if it is a personal computer or a tablet terminal, if information related to its own OS, IME, and browser is not included in the access request to the search site, a process of including this in the access request is performed. Also good.

  However, as described above, in the case of a personal computer or a tablet terminal, information about the OS, IME, and browser of the own device is included in the access request to the search site formed according to HTTP. Further, even in the case of a high-function mobile phone terminal, user agent information including the language type of the language used by the own device may be included in the access request to the search site from the beginning. In such a case, it is not necessary to provide the language type notification processing unit 308 in the terminal device 3. In this case, an existing personal computer, tablet terminal, or high-function mobile phone terminal can be used as the terminal device 3 as it is.

[Processing of Search Server Device 1]
Next, search service providing processing executed by the search server device 1 according to this embodiment described with reference to FIGS. 1 and 2 will be summarized with reference to FIGS. 3 and 4 are flowcharts for explaining the search service providing process. 5 and 6 are diagrams for explaining examples of pages constituting a search site provided to the search request source terminal device in the search service providing process. The search service providing process shown in the flowcharts of FIGS. 3 and 4 is a process that is constantly executed mainly in the control unit 102 of the search server apparatus 1.

  The control unit 102 accepts access to the search site from various terminal devices 3 connected to the network 2 through the communication I / F 101 (step S101). That is, in the processing of step S101, for example, the control unit 102 receives an access request using the URL of the search site of the search server device 1 posted in the guide book through the communication I / F 101. Then, the control unit 102 determines whether or not there is access to the search site (whether or not access is accepted) (step S102). When it is determined in step S102 that the access to the search site is not accepted, the control unit 102 repeats the process from step S101 and waits for access from the terminal device 3.

  It is assumed that it is determined in the determination process in step S102 that access to the search site from the terminal device 3 has been accepted. In this case, the control unit 102 controls the language type determination unit 107 to determine the language type of the language used by the terminal device 3 that is the access source based on the information included in the access request from the terminal device 3 (step S103). In step S103, as described above, the language type is determined based on the OS and IME information of the terminal device 3, the browser information, or the user agent information included in the access request according to the HTTP from the terminal device 3. To do. Then, the control unit 102 determines whether or not the language used in the access source terminal device 3 is Japanese based on the determination result in Step S103 (Step S104).

  If it is determined in step S104 that the language used by the terminal device 3 that is the access source is Japanese, a normal search service using Japanese is provided (step S105). That is, in step S105, the control unit 102 functions and, as shown in FIG. 5A, stores a search retrieval page in Japanese having a search site title display T1, a search character string input field N1, and a search execution button B1. The information is read out from 103 and provided to the terminal device 3 that is the access source. And the control part 102 receives the Japanese search character string from the user of the terminal device 3 input and transmitted through the said search reception page. Thereafter, the control unit 102 controls the search processing unit 108 to search the corresponding data from the search DB 105 using the received Japanese search character string, and obtain a Japanese search result as shown in FIG. 6A. This is provided to the terminal device 3 that is the access source.

  In step S105, when the search result is over a plurality of pages, the page break process according to the operation on the previous page button BT1 and the next page button BT2 shown in the lower end portion of FIG. Processing such as performing a new search process according to the input is also performed. Then, when the normal search process in step S105 is completed, the control unit 102 repeats the process from step S101 and accepts new access to the search site.

  On the other hand, it is assumed that in the determination process in step S104, it is determined that the language used for the access source terminal device 3 is not Japanese. In this case, the control unit 102 controls the UI display changing unit 109 to form a search reception page in which the character display of the UI part is changed to the language used by the terminal device 3 that is the access source. 3 (step S106). The search reception page in Japanese provided by the search server device 1 of this embodiment is, for example, as shown in FIG. 5A. Therefore, the UI display change unit 109 uses the multilingual dictionary 106 to change the Japanese display portion of the Japanese search reception page to a notation (display) corresponding to the language used by the terminal device 3 that is the access source.

  For example, it is assumed that the language used by the access source terminal device 3 is English. In this case, as shown in FIG. 5B, the UI display changing unit 109 changes the title T1 of the search site from “food shop inspection search site” to “Restaurant search site”. Further, the guidance character string “Please enter a keyword.” Attached to the search character string input field N1 is changed to “Please input a keyword”. In addition, the character “search” attached to the search execution button B1 is changed to “Search”.

  Thus, a search reception page (FIG. 5B) corresponding to the language used by the access source terminal device 3 is created from the Japanese search reception page (FIG. 5A) provided in the search server device 1, and this is stored in the terminal device 3. To provide against. In this way, the search server device 1 provides the terminal device 3 with a search reception page corresponding to the language used by the terminal device 3 that is the access source, and performs a search according to the language used by the terminal device 3 through the process of step S106. Accept a string. That is, the user of the access source terminal device 3 can input the search character string in the native language that is normally used without any sense of incongruity.

  And the control part 102 receives the request | requirement from the terminal device 3 which provided the search reception page in step S106 (step S107). In step S107, the control unit 102 determines whether or not there is a request from the terminal device 3 (whether or not the request has been accepted) (step S108). If it is determined in step S108 that the request from the terminal device 3 has not been accepted, the control unit 102 repeats the processing from step S107 and waits for a request from the terminal device 3. If it is determined in step S108 that the request from the access source terminal device 3 has been received, the control unit 102 determines whether or not the received request is a search request (step S109).

  When determining in step S109 that the request is not a search request, the control unit 102 determines whether the received request is a request to end access to the search site (step S110). Assume that in the determination process in step S110, it is determined that the request from the terminal device 3 is not a request to end access to the search site. In this case, it is determined that the request from the terminal device 3 is not accepted through the search acceptance page shown in FIG. 5B, and the processing from step S107 is repeated. Thereby, a new request from the terminal device 3 can be accepted. Further, when it is determined in the determination process of step S110 that the request from the terminal device 3 is a request for termination of access to the search site, a predetermined information such as deleting information such as the IP address of the terminal device 3 that is the access source is deleted. An end process is executed (step S111), and the processes from step S101 are repeated.

  Also, in the determination process in step S109, it is determined that the received request from the access source terminal device 3 is a search request. In this case, the control unit 102 supplies the search character string included in the received search request and the language type of the terminal device 3 determined in step S103 to the search character string translation unit 110 to translate the search character string. (Step S112). In the process of step S112, under the control of the control unit 102, the search character string translation unit 110 translates the search character string expressed in the language used by the access source terminal device 3 into a Japanese search character string.

  Then, the control unit 102 supplies the search character string translated into Japanese by the search character string translation unit 110 to the search processing unit 108, and executes search processing for extracting the corresponding data from the search DB 105 (step S113). Thereafter, the process proceeds to step S114 in FIG. Then, the control unit 102 controls the search result translation unit 111 to translate the Japanese search result acquired by the search processing unit 108 in step S113 into the language used by the terminal device 3 that is the access source, and this is translated into the access source To the terminal device 3 (step S114).

  For example, it is assumed that the language used by the access source terminal device 3 is English. In this case, the Japanese search result obtained as shown in FIG. 6A is translated into a search result expressed in English as shown in FIG. 6B. Further, in the search server device 1 of this embodiment, when there is a site corresponding to the language used by the access source terminal device 3 in the search result, the control unit 102 converts the information of the site into Japanese. Provide in preference to the site. Specifically, in the example shown in FIG. 6B, since the site of “Dining EBISU” displayed first in the search result is an English-compatible site, “for English” indicating that the site is an English-compatible site. The display H1 is added.

  Even if there is no site corresponding to the language used by the terminal device 3 in the search result, the URL of the page translation site from Japanese to the language used by the terminal device 3 is automatically generated and the search result is displayed. indicate. Specifically, in the example shown in FIG. 6B, the second and third sites displayed are Japanese sites. In this case, next to the titles of the second and third sites shown in FIG. 6B, “Translate” is a selectable display for connecting to a site that provides a service for translating the contents of the Japanese site into English. This page "display S1 and S2 are displayed. When the display S1 or S2 is selected, the corresponding Japanese site can be translated into English using the translation site, and the contents of the Japanese site translated into English can be displayed.

  As described above, the search result translation unit 111 preferentially provides a corresponding page of the language used according to the language used by the terminal device 3 that is the access source, or translates the Japanese site into the language used. It also realizes a function to provide and provide a translation function using. These functions may be realized by the control unit 102 or specially provided additional means before the translation processing by the search result translation unit 111 or after the translation processing by the search result translation unit 111, for example. Good.

  Then, the control unit 102 accepts a request from the user of the terminal device 3 input and transmitted through the search result display page (step S115), and whether or not there is a request from the user of the terminal device 3. It is determined (whether or not it has been accepted) (step S116). If it is determined in step S116 that the request from the user of the terminal device 3 has not been received, the control unit 102 repeats the processing from step S115 and waits for a request from the terminal device 3. When it is determined in step S116 that the request from the access source terminal device 3 has been received, it is determined whether or not the received request is a request to end access to the search site (step S117).

  When determining in step S117 that the request is not an end request, the control unit 102 determines whether the received request is a new search request (step S118). If it is determined in step S118 that the request is not a new search request, processing is performed according to the received request (step S119), and thereafter, the processing from step S115 is repeated. In step S119, in response to a request from the user, the above-described processing for translating the Japanese site into the language used for display, display processing for the selected Japanese site, page break processing, and the like are performed. .

  If it is determined in step S118 that the request is a new search request, the control unit 102 clears the current search result (step S120) and repeats the processing from step S106 in FIG. That is, a new search character string is received and a new search process can be performed. If it is determined in the determination process in step S117 that the received request is a request to end access to the search site, the control unit 102 deletes information such as the IP address of the terminal device 3 that is the access source. The predetermined end processing is executed (step S121), and the processing from step S101 in FIG. 3 is repeated.

  In this manner, the search server device 1 executes the search service providing process in response to access requests from various terminal devices 3.

[Effect of the embodiment]
As described above, the search server device 1 of this embodiment automatically determines the language used by the terminal device 3 that is the access source, provides a search reception page corresponding to the language used, and searches for languages other than Japanese. A character string can be accepted. Even when a search character string in a language other than Japanese is used, a search device in Japanese is searched, a search result in Japanese is obtained, and a terminal device that automatically determines this is used. It can be translated into a language and provided to the terminal device of the access source. That is, the search server device 1 can realize Japanese language search corresponding to multiple languages.

[Modifications, etc.]
In the above-described embodiment, the case where multilingual Japanese information search is realized has been described as an example. However, the present invention is not limited to this. Searching for information expressed in one multilingual language such as multilingual English information searching, multilingual Chinese information searching, and the like can be similarly realized. Accordingly, in each country, a search character string (search keyword) expressed in another language can be accepted, and a search database maintained in the native language can be searched.

  The search server device 1 according to the above-described embodiment includes the crawling unit 104 and the search DB 105, but is not limited thereto. The search DB 105 may refer to what is provided in another server device connected to the network 2. In this case, there is no need to provide the crawling unit 104 in the search server device 1. The translation functions of the UI display change unit 109, the search character string translation unit 110, and the search result translation unit 111 are requested to process the translation server provided on the network 2 to obtain the translation result. It is also possible to configure.

  In the search server device 1 according to the above-described embodiment, as described with reference to FIG. 5, the title of the search site is also changed according to the language used by the access source terminal device. It is not limited. Depending on how the search reception page is created, the search site title may not be separable as text data. In this case, since the title of the search site cannot be changed, it is not necessary to change the title of the search site. In this case, a description corresponding to the language used for the title of the search site may be added to the empty area of the search reception page, for example, “Researchant search site”. Further, the search server device 1 may have a translation function for the entire site.

  In the above-described embodiment, the function for translating a Japanese site into the language used by the terminal device is to use an existing translation site on the Internet. In this case, the usage form of the translation site is not limited to that described in the above-described embodiment. For example, by providing a translation site display in the search result page and dragging and releasing the target Japanese site to the translation site display position (so-called drag and drop operation) The Japanese site can be translated into English and displayed. That is, the process of translating and displaying the site included in the search result can be realized in various ways.

  In the above-described embodiment, in the case of a high-performance mobile phone terminal with global specifications, it has been described that the language type of the language used in the own device is included in the user agent information and transmitted. It is not limited to. What is necessary is just to be able to transmit as information identifiable on the search server device 1 side.

  Further, when the search site itself provided by the search server device 1 supports multiple languages and the search DB 105 also has a multilingual index, the UI display change unit 109 shown in FIG. The translation unit 110 may not function. In this case, it can be used just like the search site in the user's own country until just before the display of the search result. Then, the search result in Japanese may be translated and provided in accordance with the language used by the user's terminal device.

[Others]
As is clear from the description of the embodiment described above, the function of the search server device determination unit is realized by the language type determination unit 107 of the search server device 1, and the function of the search server device change unit is the search server. The UI display changing unit 109 of the device 1 is realized. The function of the first translation means of the search server device is realized by the search character string translation unit 110 of the search server device 1, and the function of the search means of the search server device is executed by the search processing unit 108 of the search server device 1. The search result translation unit 111 of the search server device 1 realizes the function of the second translation means of the search server device. The search result translation unit 111 of the search server device 1 realizes the function of the adding means of the search server device.

  The processing shown in the flowcharts of FIGS. 3 and 4 corresponds to the information search method of the present invention. Moreover, the program which performs the process according to the flowchart of FIG. 3, FIG. 4 is an information search program performed with a search server apparatus. Therefore, by forming a program for executing the processing shown in FIGS. 3 and 4 and mounting it in the search server device so that the program can be executed in the search server device, the search server device of the present invention can be facilitated. Can be realized.
